Energy storage pack box heat dissipation method

Does airflow organization affect heat dissipation behavior of container energy storage system?

In this paper, the heat dissipation behavior of the thermal management system of the container energy storage system is investigated based on the fluid dynamics simulation method. The results of the effort show that poor airflow organization of the cooling air is a significant influencing factor leading to uneven internal cell temperatures.

How do I ensure a suitable operating environment for energy storage systems?

To ensure a suitable operating environment for energy storage systems, a suitable thermal management system is particularly important.

What is energy storage system (ESS)?

The energy storage system (ESS) studied in this paper is a 1200 mm × 1780 mm × 950 mm container, which consists of 14 battery packs connected in series and arranged in two columns in the inner part of the battery container, as shown in Fig. 1. Fig. 1. Energy storage system layout.

How to reduce the temperature of a battery pack?

In optimized solution 2, the temperature of the corresponding battery packs is reduced by changing the state of the fan in battery packs 4 and 11. In optimized solution 3, the temperature of the corresponding battery pack has been significantly reduced by further changing the status of the fan in battery packs 1 and 8.

Does optimized solution 4 reduce heat dissipation?

The results show that optimized solution 4 has significantly better heat dissipation than the other solutions, with an average temperature and maximum temperature difference of 310.29 K and 4.87 K respectively, a reduction of 1.16 % and 54.36 % respectively compared to the initial scheme.

How does a cooling strategy improve temperature inhomogeneity?

This new cooling strategy improved the temperature inhomogeneity by reducing the temperature uniformity between cells by 3.2 °C and by reducing the consumed cooling flow by 38 %. Shi et al. investigated the effect of setting the air inlet on the side wall of the battery pack to the internal temperature field.
